THOM KROM M ST 537 Trousers - Black Dual-Shell Cotton Elastane Worked Knit Long Men's German

The Trouser That Moves the Way You Do.

The THOM KROM M ST 537 is a worked knit trouser in a dual-shell construction: Shell 1 in 97% cotton, 3% elastane for the primary panels, and Shell 2 in 100% cotton for the structural zones. The elastane-blended shell provides the give that knit trousers need to move through a full range of motion without restriction. The pure cotton shell provides the structure and drape at the areas that define the trouser's silhouette and fall. Long cut. German design. Turkish manufacture.

Why These Trousers Are Different

• Dual-shell worked knit construction: Two fabrics placed by panel — 97/3 cotton-elastane in the primary leg panels for stretch, 100% cotton for the structural zones that hold the trouser's shape
• 3% Elastane in Shell 1: Enough elastane for full freedom of movement through the knee, hip, and seat — the panels that require give on every step and every sit; insufficient to change the visual character or breathability of the cotton-dominant blend
• 100% Cotton Shell 2: Pure cotton at the structural zones — natural drape, breathability, and hand-feel where the trouser defines its silhouette
• Worked / gewirkt construction: Loop-built fabric throughout — inherent knit stretch amplified by the elastane in the primary panels
• Long cut: A full-length trouser with the structure and fall of a considered cut, not a casual jogger silhouette
• German design: THOM KROM construction intelligence applied to the trouser category — fabric decisions made for function and movement, not cost
• No logos: The knit construction, panel geometry, and silhouette carry the identity
• Unlike standard cotton trousers which restrict at the knee and hip under sustained movement, the M ST 537's elastane panels give precisely where the body demands it — a trouser that is as functional as it is considered

The Moment You Put Them On

The knit surface is immediately different from a woven trouser — softer, more yielding, already giving before you've taken a step. The cotton-elastane shell moves with the leg: sit, stand, climb stairs — no restriction at the knee, no pulling at the seat. The pure cotton panels hold the shape. The waistband sits without digging. The trouser falls with the weight of a considered knit, not the looseness of a casual jogger.

This is the trouser for the full day: from standing meetings to long commutes to seated dinners, without a moment of discomfort or a change of clothes.

The Art of Dual-Shell Knit in Trousers

Trouser construction in worked knit presents a specific engineering challenge: the primary leg panels must provide enough stretch to accommodate the full range of leg movement — hip flexion, knee extension, seated compression — while the structural zones must hold the trouser's silhouette and prevent the fabric from deforming under sustained wear. THOM KROM addresses this with the dual-shell approach: Shell 1 in 97% cotton, 3% elastane covers the panels that move; Shell 2 in 100% cotton covers the panels that define shape and fall. The 3% elastane content in Shell 1 sits below the threshold that changes the visual character or breathability of the fabric, but above the threshold that provides meaningful stretch recovery under sustained movement. The pure cotton Shell 2 maintains the drape and structure of the trouser's silhouette without synthetic content at the zones where the fabric's character is most visible. It is the same dual-shell logic applied to the sweat jacket range, translated into the specific movement requirements of a trouser.

How to Wear Them

• With the M SJ 706 worked knit jacket: A complete knit look — consistent cotton construction from jacket to trouser, the worked knit surface reading as a deliberate material choice across both pieces
• With the M SJ 703 or M SJ 707 dual-shell jacket: The dual-shell logic matched across both garments — the same construction intelligence at the trouser and jacket level, a technically unified look
• With the M S 197 sweatshirt: The knit trouser as the base for a full worked cotton construction — sweatshirt above, knit trouser below, a consistent material register throughout
• Travel and transit: The elastane panels handle sustained seated wear without the trouser creasing, deforming, or restricting circulation — a trouser built for the hours between departure and arrival

Care Instructions

• Machine wash cold, gentle cycle — inside out to protect knit surface texture and colour depth
• Do not tumble dry — lay flat to dry; knit trousers are particularly susceptible to leg-length stretching if hung while wet
• Do not bleach
• Low steam iron if needed — press from inside with a cloth barrier; avoid direct heat on the elastane-blend panels
• Do not dry clean
• Store folded to maintain trouser shape and prevent waistband stretching over time
